How to measure pipe diameter with ultrasonic flowmeter? Posted by : admin / Posted on : Aug 27， 2021

Many people think that the ultrasonic flowmeter is a non-contact measurement method, or that the electromagnetic flowmeter has low requirements for straight pipe sections. It is wrong. This wrong understanding is often at the expense of accuracy. In practice, the accuracy of ultrasonic flowmeters can already achieve 0.5% accuracy, and many of its advantages will be gradually reflected in future industry applications. Of course, there are many people who will refute the many shortcomings of ultrasonic flowmeters, so I hope that when selecting models, you should clarify your application conditions, and then choose the appropriate flow meter according to the operating conditions. Choose instruments with different accuracy. Only an instrument that meets your actual work needs is a good instrument.

As we all know, the current industrial flow measurement generally has the problem of large pipe diameter and large flow measurement difficulty. This is because the increase in the measurement pipe diameter will bring about difficulties in manufacturing and transportation, increasing the cost and increasing energy loss. Large and installation not only these shortcomings, but also the ultrasonic flowmeter can be avoided. Because all kinds of ultrasonic flowmeters can be installed outside the tube and non-contact flow measurement, the cost of the meter is basically independent of the diameter of the pipe to be measured, while the cost of other types of flowmeters increases greatly as the diameter increases, so the larger the diameter of the ultrasonic The function and price ratio of the flowmeter is superior to that of other types of flowmeters with the same function. Considered to be a better large pipe diameter flow measuring instrument, the Doppler ultrasonic flowmeter can measure the flow of two-phase media, so it can be used for the measurement of sewage and sewage and other dirty flows.

In power plants, it is much more convenient to use portable ultrasonic flowmeters to measure the flow rate of large pipe diameters such as the water inflow of the water turbine and the circulating water of the steam turbine. Ultrasonic wasted juice can also be used for gas measurement. The applicable range of pipe diameter is from 2cm to 5m, from open channels and culverts with a width of several meters to rivers with a width of 500m.
